This article tries to provide elements of discussion and reflection rather than answers to the following question: for many centuries or even millennia, man, at least in so far as prehistory and history have recorded it, made a close connection between the beautiful, the true and the useful and he sought an aesthetic response in the minute manifestations of his daily existence as well as of his intellectual life. Today, and even more so for just the past fifty or one hundred years, art seems to be relegated to specific domains, expelled from the daily life of the average person. Yesterday, and for centuries and millennia, mankind was not satisfied with the fact that a house, a temple, a church, a fortification or a castle were lodgings, proper places to hold reunions, strong-holds built for a particular purpose, it was equally important that they be beautiful; a key did not only have to open a lock, a carriage had not only to run, a bit to control a horse, spurs to reassure the rider, a glass pane to close a window, a table to have a place setting, a chest of drawers to contain clothes, clothes to cover the body, a pen to write, a manuscript to transmit the signs of the alphabet—no, it was also necessary that these signs, that manuscript, the pen, the spurs, the bit, the key … be designed and decorated in such a way so as to evoke in the persons who merely saw them, without even using them, an affective emotion of beauty. Nor was it enough that science or a technique be true or useful, they had also to be beautiful.
